Two business locations merging to one new office

We are a real estate company that currently has two locations in Gainesville, FL. In two weeks, we will be moving to a new office and merging the offices together under one roof. So far, I have managed two separate Google My Business pages for each of the locations. I am not sure what to do now that we will have one office instead of two and it will be a new address. I am not sure if I should "close" one of the locations and update the other with the new address since we are not technically closed, we are just moving. Also, one of our profiles has a lot of reviews and I don't want to lose those. Please guide me on my next steps, thanks.

Tim, I got as far as deleting Page B. I have gone to the support/contactflow page but I do not see where I can let someone know that the page needs to be moved to Page C. Can you elaborate on that step?
